Gentle, non-irritating Gargrin Zero

The first thing I do when I wake up in the morning is use Gargrin. It is essential because a lot of bacteria accumulate in my mouth overnight. I have tried various products, but I found it burdensome to use spicy or irritating ones every day. That is why I only use Gargrin Zero. When I switch from the Original to Zero, I can definitely feel that it is milder. It doesn't mean the effectiveness is compromised; in fact, I prefer it because it is ethanol-free. If you found Gargrin too irritating, give Zero a try!
